GOLD RECOVERY FROM COPPER GOLD GRAVITY …
Leaching Gravity concentrate samples were obtained from Brown's Creek and used in a series of tests to investigate gold and copper leaching under intensive cyanidation conditions. Tests were conducted in rolling bottles with solution samples taken during the leaches to establish gold and copper leaching kinetics and reagent consumption.

leaching techniques | Gold Refining & Metal Extraction Forum
If the gold is free gold, and not invisible in the ore I would concentrate it with gravity or some other method, before trying a leach. If you are going to leach the gold you should first get analysis of the ore, to determine the metals it contains and also the chemical makeup, then you have a better understanding of what may or may not work ...

How to Extract Gold From Ore? | miningpedia
Therefore, the gravity separation method is mostly used to select placer gold and vein gold before and after flotation and leaching to recover coarse-grained gold from monomer dissociation. Generally, the lower limit of the particle size of gold that can be recovered by the gravity separation method is 0.01 mm.

APHRODITE GOLD DEPOSIT POSITIVE …
Diagnostic leaching and QEMSCAN analysis show that there is more gold associated with arsenopyrite than pyrite. It may therefore be possible to selectively float arsenopyrite from other sulphides to produce an even lower mass concentrate at extremely high gold grade (Note 2). This needs to be demonstrated in future testwork.

Chlorine leach | Gold Refining & Metal Extraction Forum
Cant float it unless the gold is in a sulfide or telluride (original poster wont say). Can't gravity concentrate it if the gold is micron sized as the original poster mentioned. One thing about chlorine leaching is that it requires acidic conditions - not necessarily strong acid, but at least mildly acidic.
